CVE-2007-2754

Status Candidate

Overview

Integer signedness error in truetype/ttgload.c in Freetype 2.3.4 and earlier might allow remote attackers to execute arbitrary code via a crafted TTF image with a negative n_points value, which leads to an integer overflow and heap-based buffer overflow.

Authored by OpenPKG Foundation | Site openpkg.com

OpenPKG Security Advisory - A vulnerability caused by an integer signedness error was found by Victor Stinner in the font rendering library Freetype, versions up to and including 2.3.4. The vulnerability might allow remote attackers to execute arbitrary code via a specially crafted TrueType Font (TTF) file with a negative "n_points" value, which leads to an integer overflow and heap-based buffer overflow.
